Abstract
The utility model discloses a quick coupling for an indoor unit of an air conditioner. The quick coupling is used for connection of an evaporator and a connecting pipe and comprises a horizontal cavity and a vertical cavity. One end of the horizontal cavity is provided with a connecting port, and the other end of the horizontal cavity is provided with a sliding valve. One end of the vertical cavity is provided with a fluorine filling valve, and the other end of the vertical cavity is provided with a stop valve. Due to the fact that the fluorine filling valve used for filling refrigerants is additionally arranged on the quick coupling for the indoor unit of the air conditioner, the refrigerants can be filled automatically from the indoor side of the air conditioner, and professional maintenance personnel are not needed for the filling of the refrigerants from the outdoor side by working aloft. Therefore, not only is use cost lowered, but also life safety of the maintenance personnel is guaranteed. The fluorine filling valve can also be connected with a pressure gage so that whether the refrigerants in the air conditioner are leaked or not can be judged through observation of the pressure gage, and therefore potential safety hazards such as overburning of a compressor and explosion of a compressor cylinder body caused by entry of air into the compressor are avoided. Besides, the refrigerants can be prevented from leaking in the assembling or maintaining process of the air conditioner through control of the stop valve so that the assembling is enabled to be safer and more environmental friendly.

Based on above-described embodiment, the part that offsets on sliding sleeve 125 and slide-valve push rod 124 trumpet-shaped surfaces is provided with a sealing gasket 131.Sealing pad 131 the further sealing that guarantees slide-valve 12, the more effective leakage that prevents cold-producing medium be set.
In the lump with reference to Fig. 4, Fig. 4 is the structural representation of annotating the fluorine valve in the snap joint of the utility model indoor apparatus of air conditioner.
In the above-described embodiments, annotating fluorine valve 21 specifically comprises: valve inside sleeve pipe 211, valve inside push rod 212 and valve inside spring 213.Wherein, valve inside sleeve pipe 211 and vertical chamber 20 are adaptive and be placed in the vertical chamber 20, and its outer wall is spirally connected with the vertical inwall in chamber 20.
Valve inside push rod 212 runs through valve inside sleeve pipe 211, its diameter is slightly less than the internal diameter of valve inside sleeve pipe 211, one end of valve inside push rod 212 is provided with a groove, be provided with an O-ring seal 215 in this groove, be used for the space that produces less than the internal diameter of valve inside sleeve pipe 211 because of the external diameter of valve inside push rod 212.
Valve inside spring 213 1 ends are fixedly connected with valve inside push rod 212, and the other end is fixedly connected with valve inside sleeve pipe 211.Valve inside spring 213 is preferably and is the taper setting, and the surface of valve inside push rod 212 is provided with positive stop lug boss, and the larger end of valve inside spring 213 is supported on the sidewall of valve inside sleeve pipe 211, supports than small end on the positive stop lug boss on valve inside push rod 212 surfaces.Valve inside push rod 212 is provided with a round platform with respect to the other end that is provided with O-ring seal 215.When an External Force Acting was on the round platform of valve inside push rod 212, valve inside spring 213 was compressed, and O-ring seal 215 breaks away from valve inside sleeve pipe 211, and forms a refrigerant passage between valve inside sleeve pipe 211 and valve inside push rod 212; After this external force removed, valve inside spring 213 elasticity were recovered, and O-ring seal 215 and valve inside sleeve pipe 211 are close to, with the sealing of the space between valve inside push rod 212 and the valve inside sleeve pipe 211, block refrigerant path.
When needs filling cold-producing medium, to be connected with notes fluorine valve 21 afterwards with the fluorine bottle connector of thimble is emptying, the masterpiece of the thimble of fluorine bottle is used on the round platform of valve inside push rod 212, valve inside spring 213 is compressed, O-ring seal 215 breaks away from valve inside sleeve pipe 211, and forms a refrigerant passage between valve inside sleeve pipe 211 and valve inside push rod 212.Because during operation of air conditioner, the pressure of snap joint place of indoor apparatus of air conditioner is far smaller than the pressure in the fluorine bottle, thus the notes fluorine valve 21 of the cold-producing medium of fluorine bottle by the snap joint of indoor apparatus of air conditioner be inhaled in the air-conditioning system, thereby finish the filling cold-producing medium.After filling was finished, because the effect of valve inside spring 213, O-ring seal 215 was close to rapid and valve inside sleeve pipe 211, and with the sealing of the space between valve inside push rod 212 and the valve inside sleeve pipe 211, the block refrigerant path prevents the leakage of cold-producing medium.
Based on above-described embodiment, also can be provided with seal rubber sleeve 214 between valve inside sleeve pipe 211 and the vertical chamber 20.Sealing gum cover 214 can be filled the gap between valve inside sleeve pipe 211 and the vertical chamber 20 fully, has guaranteed to annotate fluorine valve 21 and has had good sealing.
In the lump with reference to Fig. 5, Fig. 5 is the structural representation of stop valve in the snap joint of the utility model indoor apparatus of air conditioner.
In the above-described embodiments, stop valve 22 specifically comprises a sealing column 221 that is spirally connected with vertical chamber 20 inwalls, sealing post 221 is with vertically chamber 20 is suitable, when turning sealing column 221, sealing column 221 is moved to annotate fluorine valve 21 places, and when offseting with the inwall of annotating fluorine valve 21, sealing post 221 is with connector 11, slide-valve 12 and annotate fluorine valve 21 seal isolation, making it not to be communicated with mutually, is independent each other; When oppositely turning sealing column 221, when sealing column 221 was moved to the direction away from notes fluorine valve 21, connector 11, slide-valve 12 and notes fluorine valve 21 communicated with each other.
Control by stop valve 22 can make connector 11, slide-valve 12 and annotate each other seal isolation/mutual conduction of fluorine valve 21, has avoided in the process of air-conditioning assembling or maintenance refrigrant leakage occuring, and has further guaranteed the safety and environment protection of assembling.
Based on above-described embodiment, sealing column 221 is rounded corner 223 settings with the end face that notes fluorine valve 21 offsets, and the surface that notes fluorine valve 21 contacts with sealing column 221 and rounded corner 223 shapes of sealing column 221 are adaptive.The end face that rounded corner 223 arranges has increased sealing column 221 and the area of annotating fluorine valve 21 and contact, has strengthened its sealing, and when having guaranteed that stop valve 22 is screwed to, connector 11, slide-valve 12 and notes fluorine valve 21 isolate each other fully.
Based on above-described embodiment, the surface of sealing column 221 is provided with a groove, is provided with the 4th sealing ring 222 in this groove.The 4th sealing ring 222 is arranged between sealing column 221 and vertical chamber 20 inwalls, has guaranteed the sealing of stop valve 22.
Based on above-described embodiment, be provided with in the port of stop valve 21 for the Non-return ring 224 spacing to sealing column 221.This Non-return ring 224 can prevent that sealing column 221 from twisting excessively and withdrawing from stop valve 21.
